EVALUATION


Need to add the following methods:

VolatileImage.java:
	public void flush()

GraphicsDevice.java:
	public int getAvailableAcceleratedMemory()

The flush() method is actually already in VolatileImage; the method is
inherited from Image.java.  However, that method is currently stubbed out.
We need to define the new meaning of that method clearly in comments
and implement the code that makes this work.  An important concern in
implementing this functionality is MT-safety: we need to put new locks around
all ddraw surface accesses to make sure that other threads are not referring
to the underlying ddraw surface at the same time as we are releasing it.

The getAvailableAcceleratedMemory() would be a new method in GraphicsDevice.
The only trick in implementing this is that some platforms (i.e., NT4) do not
really support inquiries about video memory availability.  Our implementation
would need to trap that error case (where the free memory was always reported
as "0") and manually discover how much memory is there.  This can be done
by simply creating as many surfaces as possible (and then releasing
those temporary surfaces...) and reporting how many bytes were successfully
allocated.
